김성원,이영준 한국컴퓨터정보학회 2020 韓國컴퓨터情報學會論文誌 Vol.25 No.7

본 연구에서는 김성원과 이영준(2019)의 프로그래밍 기반 TPACK 교육 프로그램이 예비 교사의 수업전문성에 미치는 효과를 분석하였다. 연구 대상은 40명의 예비 교사이며, 두 집단으로 나누어 처치를진행하였다. 실험 집단(n=20)에게는 프로그래밍 기반 TPACK 교육 프로그램을 처치하고, 통제 집단(n=20)에게는 ICT 도구 기반 TPACK 교육 프로그램을 적용하였다. 예비 교사의 수업 전문성 변화를분석하기 위하여 수업 전문성, 교수 효능감, 테크놀로지 통합 자아효능감을 측정하는 검사 도구를 사용하였다. 연구 결과, 통제 집단과 달리 실험 집단은 수업 전문성과 교수 효능감, 테크놀로지 통합 자아효능감이 유의하게 향상되었다. 사전 검사에서는 실험 집단과 통제 집단이 유의한 차이가 존재하지 않았지만, 사후 검사에서는 실험 집단이 통제 집단보다 수업 전문성이 유의하게 높았다. 이러한 결과를 통하여프로그래밍을 활용한 TPACK 교육이 예비 교사의 수업 전문성 발달에 효과적인 것을 확인할 수 있었다. This study analyzes the effects of programming-based TPACK education programs, designed by Kim and Lee (2019), on the teaching expertise of pre-service teachers. The research subjects were 40 pre-service teachers, divided into an experimental group and a control group. The experimental group underwent the programming-based TPACK education program, and the control group used an ICT-based TPACK education program. A test tool was used to measure not only teaching expertise but also teaching efficacy and self-efficacy beliefs about technology integration. As a result of the study, teaching expertise, teaching efficacy, and self-efficacy beliefs about technology integration improved significantly in the experimental group. The pretest showed no significant difference between the experimental group and the control group, but in the post-test, the experimental group showed significantly higher teaching expertise than the control group. These results showed that the programming-based TPACK education program is effective for developing teaching expertise in pre-service teachers.

This study aims to verify the effectiveness of the programming-based TPACK educational program developed by Kim and Lee (2019) in improving the TPACK of pre-service teachers. The treatment used ICT-based (control) and programming-based TPACK educational programs (first, second, third, and final cycle) developed through design-based research. TPACK test tools were implemented pre and post treatment, and the test results were analyzed using ANCOVA. Therefore, the TPACK of pre-service teachers who implemented the programming-based TPACK educational program was significantly higher compared to the ICT-based TPACK educational program. Furthermore, through this design-based research, the effect of the developed final educational program on the TPACK of pre-service teachers was particularly the most outstanding. Therefore, it can be concluded that the programming-based TPACK education program developed through design-based research is effective in improving the TPACK of pre-service teachers. 본 연구에서는 김성원과 이영준(2019)에서 개발한 프로그래밍 기반 TPACK 교육 프로그램을 검증하는 연구이다. 연구에서 처치는 설계 기반 연구를 통하여 개발한 프로그래밍 기반 TPACK 교육 프로그램(1차, 2차, 3차, 최종)과 ICT 기반 TPACK 교육 프로그램을 사용하였다. 교육 프로그램의 효과를 분석하기 위하여 사전, 사후에 TPACK 검사 도구를 실시하였으며, 검사 결과는 ANCOVA를 통하여 분석하였다. 적용 결과, 프로그래밍 기반 TPACK 교육 프로그램을 적용한 예비 교사의 TPACK은 ICT 기반 TPACK 교육 프로그램보다 유의하게 높았다. 특히 설계 기반 연구를 통하여 최종적으로 개발한 교육 프로그램이 예비 교사의 TPACK 발달에 가장 효과적이었다. 이러한 연구를 통하여 설계 기반 연구를 통하여 예비 교사의 TPACK 향상에 효과적인 프로그래밍 기반 TPACK 교육 프로그램을 개발하였다는 것을 확인하였다.

Purpose: The objective of this study was to evaluate the change in the practice patterns for managing hereditary breast and ovarian cancer (HBOC) among Korean physicians after the Korean Hereditary Breast Cancer (KOHBRA) study. Methods: The first survey was performed from July to August 2007, at the initiation of the KOHBRA study, and the followup survey was conducted from July to December 2009. Members of the Korean Breast Cancer Society were invited to participate in the study by e-mail. The 2009 survey was conducted with a self-administered questionnaire concerning HBOC management and was identical to the previous questionnaire. Results: According to the 2009 survey, most physicians (60.0%) tended to draw a pedigree (48.0% in 2007 survey). The rate of genetic test recommendations for patients at risk for HBOC was higher in the 2009 survey (84.0%) than that in the 2007 survey (64.0%). Physicians tended to select a BRCA genetic testing candidate more appropriately than in the previous survey (42.4% answered right in 2007 survey; 74.4% in 2009 survey). Fifteen of 25 participants (60.0%) provided genetic counseling before their patients underwent a genetic test, which was higher than that (40.0%) in the 2007survey. According to the 2009 survey, half of the genetic counseling was being conducted by KOHBRA study research nurses; whereas most of the genetic counseling was conducted by physicians in 2007. Conclusion: The KOHBRA study has played an important role in the appropriate selection of candidates for genetic testing. However, more effort should be placed on improving the pre-test genetic counseling rate.

We report several experimental data capable of evaluating the amorphous-to-crystalline (a-c) phase transformation in $(Ag)_x(Ge_2Sb_2Te_5)_{1-x}$ (x = 0, 0.05, 0.1) thin films prepared by a thermal evaporation. The isothermal a-c structural phase changes were evaluated by XRD, and the optical transmittance was measured in the wavelength range of $800{\sim}3000$ nm using a UV-vis-IR spectrophotometer. A speed of the a-c transition was evaluated by detecting the reflection response signals using a nano-pulse scanner with 658 nm laser diode (power P = $1{\sim}17$ mW, pulse duration t = $10{\sim}460$ ns). The surface morphology and roughness of the films were imaged by AFM. It was found that the crystallization speed was so enhanced with an increase of Ag content. While the sheet resistance of c-phase $(Ag)_x(Ge_2Sb_2Te_5)_{1-x}$ was similar to that of c-phase $Ge_2Sb_2Te_5$ (i.e., $R_c{\sim}10{\Omega}/{\square}$), the sheet resistance of a-phase $(Ag)_x(Ge_2Sb_2Te_5)_{1-x}$ was found to be lager than that of a-phase $Ge_2Sb_2Te_5$, $R_a{\sim}5{\times}10^6{\Omega}{/\square}$. For example, the ratios of $R_a/R_c$ for $Ge_2Sb_2Te_5$ and $(Ag)_{0.1}(Ge_2Sb_2Te_5)_{0.9}$ were approximately $5{\times}10^5$ and $5{\times}10^6$, respectively.

Background and Objectives:Recently, organ-preserving transoral CO_2 laser surgery have been introduced for hypopharyngeal cancer. The aim of this study was to define when CO_2 laser surgery of hypopharyngeal cancer is indicated and to evaluate the oncologic local control rate, functional results, and postoperative complications. Subjects and Method:A retrospective review of 6 patients undergoing transoral CO_2 laser microsurgery for the treatment of squamous cell carcinomas of the hypopharynx involving posterior pharyngeal wall (2 patients), pyriform sinus (4 patients) from May 2006 to December 2010 was undertaken. There were three patients with staging T3, underwent transoral CO_2 laser surgery to remove residual cancer after the induction chemotherapy. The median follow-up interval was 32 months. Results:Five out of six cases showed no local recurrence. One patient with pyriform sinus cancer died with the local recurrence and lymph node metastasis, and local control rate during follow up was 83.3%. One patient died due to brain metastasis in the postoperative 24 months, other patient died due to second primary esophageal cancer in the postoperative 36 months. There were 2 cases of surgical complications; dysphagia due to temporary esophageal stricture and primary site’s bleeding. Conclusions:Although more number of cases and time are needed, in some carefully selected cases of the early staging and advanced hypopharyngeal cancer after induction chemotherapy, transoral CO_2 laser surgery can be one of the choice.

On the premise that it is effective and necessary to make use of science magazines among any other media, the desirable direction of science magazines and, further more and the merits of magazines to promote the development of good science magazines are suggested. To see the present status of science magazines in Korea, we analyzed the public view on the science magazines by secondary school students and science teachers. We also assorted and analyzed the contents through the subjects of the issues of three major magazines published in 1991. Through the interview with the editor staffs of each magazine, the characteristics of each magazine and the editers' hopes to present the direction in the future were analyzed. As a result, the basic conditions which science magazines should equip and the required conditions to apply the basic conditions to make them better were suggested.

한국사회 양극화와 기독교의 삼위일체론적 공동체성

김성원 기독교학문연구회 2023 신앙과 학문 Vol.28 No.2

Today, Korean society is experiencing extreme bipolarization. Politically, public opinion is almost exactly divided in half along the structure of extreme confrontation between the left and the right, and political antagonism among families, work, and friends is widely noticed. Along with this political conflicts, regional sentiments and opinions concerning women’s rights are also worrisomely divided. Economically, neo-liberal capitalism divides society between the super-rich capitalists and the rest in a 1:99 ratio, which becomes a major factor in growing social unrest today. If we zoom out to see the mega-trends today, philosophies such as individualistic humanism and postmodernism are alienating many young people from meaningful social relationships. These unfortunate trends seem to only grow stronger by the technological revolutions of the fourth industrial revolution and the COVID-19 pandemic. In this quarantined, hyper-connected society we are driven into thorough isolation where there is no hope for communal life. This article seeks to find a way to resolve the deepening political, economic, and cultural bipolarization problems of today's Korean society from a Christian perspective. For that purpose this article focuses on the ideal communality underlying the Christian faith. Specifically this article focuses on the trinitarian communality of God, which is the original source of Christian communality. By introducing and discussing Social Trinitarianism – a contemporary theological interpretation of the Trinity – this article discovers essential principles from divine, social nature of the Trinity. This article further argues that the principles of divine communality shown by the Trinity can be applied to human society as viable principles of communality. The evidence for such a claim is the existence of family and the church. Christian theology recognizes the family and the church as two communities established by God, and that the trinitarian principles of communality operate within these human communities. In conclusion, this article suggests that the divine principles of communality found in the Trinity and operating in family and the church may become a solution for remedying the bipolarizing Korean society. 오늘날 한국사회는 극심한 양극화를 겪고 있다. 정치적으로는 좌파와 우파의 극단적 대립의 구도를 따라 국민들의 여론도 거의 정확하게 양분되어 가족과 직장과 친구들 사이에서도 반목을 피할 수 없다. 이러한 정치적 구도와 함께 지역감정과 남녀간의 갈등과 대립도 우려스러울 정도로 심화되고 있다. 경제적으로도 신자유주의적 자본주의는 사회를 거대자본가들과 나머지 경제주체들을 1대 99로 계급화하고 있어 큰 사회적 불안요인이 되고 있다. 문화적으로도 개인주의적 인본주의나, 포스트 모던주의, 그리고 최근의 코로나 바이러스 19 사태는 사람들을 사회생활로부터 소외시키고 있으며, 공동체 형성을 불가능하게 만들어 철저히 고립된 개인으로 몰아가고 있다. 이 논문은 오늘날 이처럼 심화되어가는 한국사회의 정치적, 경제적, 문화적 양극화 문제를 해소할 방안을 기독교적 관점에서 모색한다. 이 논문이 주목하는 양극화에 대한 기독교의 대안은 기독교 신앙의 저변에 있는 본질적 공동체성이다. 이 논문은 구체적으로 기독교의 공동체성에 근원이 되는 하나님의 삼위일체적 공동체성을 제시한다. 삼위일체에 대한 고전적 교리에 기초하여 현대신학자들의 사회적 삼위일체론을 소개하면서 이 논문은 그 속에서 사회적 공동체성의 본질적인 원리들을 발견한다. 이 논문은 더 나아가 삼위일체가 보여주는 이러한 완전한 공동체성의 원리들이 인간 사회에서도 적용되고 공동체성의 원리가 될 수 있다고 주장한다. 그 근거로 이 논문은 가정 공동체와 교회 공동체를 제시한다. 기독교 신학은 가정과 교회가 하나님이 직접 세우신 두 개의 공동체로 인식하며, 이 공동체들에서는 삼위일체적 공동체성의 원리들이 작동한다고 인식하기 때문이다. 결론적으로 이 논문은 가정과 교회에서 작동하는 공동체성의 원리들이 한국사회의 무너진 공동체성을 회복하는 하나의 중요한 대안이 될 것이라고 제안하며 구체적인 시사점과 적용점들을 예시한다.
